Title: Memory element of field effect element
Inventor: NAKAGAWA KIYOKAZU
IPC: H01L29/78
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To allow memory function using a single field effect transistor by applying an electric field to a gate for a carrier in a channel to move into a trap region, and changing a drain current amount, based on presence of electric charge amount in trap. SOLUTION: An Si layer and an Si1- XGeX mixed-crystalline layer are lattice- conformed to an Si1- XGeX mixed-crystal for growth, so that Si layer such as biaxial tensile stress is applied is formed. A fine Si crystal region is embedded in the Si1- XGeX mixed-crystal of a barrier layer to indicate a specified band structure. Thus when a positive voltage is applied to a gate electrode, electrons in a channel are confined in a fine Si crystal region through tunnel effect. In this state, a region close to a channel is charged negative so that a drain current is reduced. By monitoring changes in the current amount, whether fine crystal regions are charged or not is discriminated.

Filed: 1986-12-26
Abstract: PURPOSE:To eliminate the generation of a bit line through current in reading operation by setting the threshold voltage of a transistor (TR) for bit-line precharging equalization smaller than the threshold voltage of a normally on type bit-line pull-up TR. CONSTITUTION:The threshold voltages of N channel TRs Q3 and Q4 for bit-line precharging of a bit-line precharging equalization circuit 1 connected between a bit line couple BL for each column of a memory cell array and a VDD power source node or between a data line couple connected to plural columns in common and the VDD power source node are set smaller than the threshold voltages of normally on type N channel TRs Q1 and Q2 for bit-line pulling-up connected between the bit line couple BL for each column and the VDD power source node. Therefore, the bit-line pull-up TRs turn off from bit-line precharging equalizing operation in reading operation to a drop in the potential of the low- potential side bit line of the bit line couple below a specific value. Consequently, no through current path is formed on the bit lines.

Title: Image conversion device
Inventor: KURASHIGE MASAFUMI
IPC: G06T1/00
Filed: 1995-11-11
Abstract: PROBLEM TO BE SOLVED: To convert an input image into a line drawing like in real time. SOLUTION: The edge signal of an input image that is detected by an edge detection means 2 is normalized by a normalization means 3 and then undergoes the nonlinear conversion 4 to decrease its halftone components. Such a converted edge signal is used as a key signal for mixture of two signals. These operations can be carried out in the simple processing such as the multiplication or addition. Thus it is possible to obtain in real time such a line drawing like where only the edge having a large contrast change is extracted out of the input image.

Filed: 1991-11-05
Abstract: PURPOSE: To surely prevent the meandering of a handrail so as to prolong the life thereof by setting the swinging angles of drive rollers in both sides of the handrail equal to each other, and disposing the drive rollers always in opposing positions sandwiching the handrail. CONSTITUTION: Assuming that a handrail 18 travels from left to right in the drawing, rollers 8 and 10 are joined to the handrail 18 by specified fastening forces, and the inner races of bearings 26 and 30 are rotated in the directions of arrows A and B. At this time, the axes 13 and 15 of shafts 12 and 14 are swung by angles σ1 and σ2 respectively with respect to the axes of bearings 27 and 35. When there is no connection to be made with a link 50, since the roller 10 is brought into contact with the high friction surface of the handrail 18 and the roller 8 is brought into contact with a low friction surface at the time of applying a high load, the angle σ1 is about 25 times larger than the angle σ2 . However, the angles σ1 and σ2 are held roughly equal by the link 50.  Thus, the rollers 8 and 10 are surely brought into contact with both sides of the handrail 18 in opposing positions.

Abstract: PURPOSE: To provide a locking device of automatic vending machine capable of improving security and preventing the theft of commodities, takings, etc. CONSTITUTION: At the time of opening a door, a maintenance man inserts a key 15a into a key hole 17 to unlock a 1st locking mechanism 15. Even when the 1st locking mechanism 15 is unlocked, a 2nd locking mechanism 100 is locked during the period of previoulsy stored time information, e.g. 6 p.m. to 6 a.m., so that a door can not be opened. Thereby, commodities and a charged money in the automatic vending machine can be prevented from being stolen. Since a thief can not attain a theft purpose until the 2nd locking mechanism 100 is unlocked, the probability of giving up an attempt of theft is high. Since it is supposed that the theft at a time band other than 6 p.m. to 6 a.m. is less, the 2nd locking mechanism 100 is left unlocked. In this case, the door can be opened only by unlocking the 1st locking mechanism 15.
